At some latitudes of the Earth there are belts of high and low pressure. For example, above the equator the atmospheric pressure is lower because the surface of the earth there is very hot. Strong global winds, called westerlies and trade winds, blow from the belts high pressure towards low pressure zones. They, however, do not move directly from south to north and from north to south. This occurs because the rotation of the Earth forces global winds to turn sideways.

trade winds, monsoons, breezes.
Trade winds are formed due to pressure differences in the tropical regions of both hemispheres and at the equator. These winds are deflected by the rotation of the Earth: trade winds northern hemisphere blow from northeast to southwest, and the southern trade winds blow from southeast to northwest. They are quite stable in temperature and humidity and are one of the most important factors in climate formation.
Monsoons are formed due to pressure differences resulting from temperature differences. A distinctive property of monsoons is that during the warm and cold seasons they are directed in opposite directions: from sea to land and from land to sea. In winter, the air over the sea is warmer than over the land, the atmospheric pressure over the sea is lower, therefore, the monsoons are directed from the land to the sea. In the warm season, it’s the other way around: the air is warmer over land, and an area forms there low blood pressure. At this time, monsoons blow onto land and bring with them heavy rainfall.
IN tropical zone Monsoons are especially active, but they also exist outside the tropics. Monsoon-dominated areas are characterized by very humid summers. An excellent example of the impact of monsoons is India, where the Himalayan mountains stop the humid wind, so northern India, Burma, and Nepal receive huge amounts of rainfall.
Breezes, like monsoons, change their direction to the opposite, but this happens every day. These are not very large-scale winds; they form near seas, oceans, large lakes, and rivers. During the day, the air over land heats up, warm air rises, and is replaced by cooler air from the water. At night, on the contrary, it is warmer over the water; colder temperatures come here from the land. air masses. Thus, during the day the breeze blows from water to land, and at night - from land to water.

The first cat is actually right!!! !
you're lazy! not such a difficult question!
oh well... I'll help you with one type of wind... .
If you know, warm air rises up and cold air goes down.
Because of this constant mixing, SOME of the winds are formed
another thing... so interesting is that ALL large whirlwinds, tornadoes and hurricanes spin according to a CERTAIN PATTERN, which is known to people who know about the force of CORIOLIS. (such a scientist)
all LARGE air vortices in the northern hemisphere will spin COUNTERclockwise
and in southern hemisphere Clockwise.
I won't explain everything. this is physics. I gave a 90-minute report on this issue at the university)
Good luck)

1. Show on the globe the placement of low and high pressure belts. In which of them is the ascending air movement predominant, in which is the downward movement and what effect does this have on precipitation?

You have already seen that there is a relationship between atmospheric pressure and precipitation. At upward movement air conditions for the occurrence of precipitation are greater than with descending air. Changes in pressure are necessarily taken into account when forecasting weather. If a stable high atmospheric pressure has formed, then the weather becomes clear (hot in summer and frosty in winter), and if the pressure changes sharply from high to low, then the weather also changes sharply, the wind increases, and precipitation forms.

2. Name the constant winds over the earth's surface and explain their formation.

Trade winds and westerly winds temperate latitudes. In addition to them, constant winds include monsoons. Remember how the summer and winter monsoons blow. The reason for the formation of all winds is the difference in atmospheric pressure. The greater the wind speed more difference between pressure.

3. What effect do air currents have on climate?

Each climate zone is characterized by its own circulation of air masses. In the main climatic zones, as a rule, the air mass corresponding to the name of the given zone prevails (in the equatorial - equatorial air masses, in the tropical - tropical, in the temperate - moderate, in the Arctic - Arctic, and in the Antarctic - Antarctic).

4. How do transitional belts differ from the main ones?

IN transitional belts(subtropical, subequatorial, subarctic and subantarctic) air masses vary depending on the season of the year. In summer there is a global shift of the entire circulation to the north, in winter - to the south. Thus, in temperate zone In summer, subtropical and even tropical air masses can arrive, and in winter, subarctic and arctic ones.

5. What are the patterns of temperature distribution and precipitation on Earth?

By studying the climate map, you can identify some patterns in the distribution of heat and moisture over the Earth's surface. The amount of heat received by the Earth's surface increases as it approaches the equator. There is also more precipitation near the equator on the southeastern coasts of the continents.

6. Why are scientists around the world concerned about the state of the atmosphere?

The state of the Earth's atmosphere has changed greatly over the past 1000 years. The amount in the atmosphere has increased carbon dioxide and other pollutants. This led to the emergence of " greenhouse effect"and the gradual warming of the climate, which worries scientists very much, since the consequences threaten the lives of the entire population of the Earth.

1. Show on the globe the placement of low and high pressure belts. In which of them is the ascending air movement predominant, in which is the downward movement and what effect does this have on precipitation?

You will be able to complete the first part of the task yourself, relying on the text and pictures in the textbook (7, Fig. 16, 17).

You have already seen that there is a relationship between atmospheric pressure and precipitation. With upward movement of air, there are more conditions for the occurrence of precipitation than with downward movement. Changes in pressure are necessarily taken into account when forecasting weather. If a stable high atmospheric pressure has formed, then the weather becomes clear (hot in summer and frosty in winter), and if the pressure changes sharply from high to low, then the weather also changes sharply, the wind increases, and precipitation forms.

2. How does the weather in your area change when atmospheric pressure increases or decreases?

You will be able to answer this question yourself, based on our reasoning, as well as on the text and pictures in the textbook (7, 8).

3. Name the constant winds over the earth's surface and explain their formation.

In the 7th textbook, such constant winds as trade winds and westerly winds of temperate latitudes were already named. In addition to them, constant winds include monsoons. Remember how the summer and winter monsoons blow. The reason for the formation of all winds is the difference in atmospheric pressure. The greater the difference between the pressures, the greater the wind speed.

4. What causes frequent weather changes in your area?

You will be able to answer this question yourself, based on the text and pictures in the textbook (7, 8), as well as on the messages

about the weather in your area on radio and television.

5. What effect do air currents have on climate?

Each climate zone is characterized by its own circulation of air masses. In the main climatic zones, as a rule, the air mass corresponding to the name of the given zone prevails (in the equatorial - equatorial air masses, in the tropical - tropical, in the temperate - moderate, in the Arctic - Arctic, and in the Antarctic - Antarctic).

6. How do transitional belts differ from the main ones?

In transitional zones (subtropical, subequatorial, subarctic and subantarctic), air masses change depending on the season of the year. In summer there is a global shift of the entire circulation to the north, in winter - to the south. Thus, subtropical and even tropical air masses can enter the temperate zone in summer, and subarctic and arctic ones in winter.

7. In what climatic zone do you live?
8. What weather prevails in the tropical zone?

You can answer these questions yourself, based on the text and pictures in the textbook (7, 8) and the maps in the school atlas.

9. What are the patterns of temperature distribution and precipitation on Earth?

By studying the climate map, you can identify some patterns in the distribution of heat and moisture over the Earth's surface. The amount of heat received by the Earth's surface increases as it approaches the equator. There is also more precipitation near the equator on the southeastern coasts of the continents.

10. Why are scientists around the world concerned about the state of the atmosphere?

The state of the Earth's atmosphere has changed greatly over the past 1000 years. The amount of carbon dioxide and other pollutants in the atmosphere has increased. This has led to the emergence of the “greenhouse effect” and gradual warming of the climate, which worries scientists very much, since the consequences threaten the lives of the entire population of the Earth.
